Beit known thatI, ANDREW VVIRSING, a `citizen of theyUnited States,andanresident of Milwauke in the'county of Milwaukee and` State ofWisconsin, haveinvented certain new and useful Improvements inI-Ioisting-Bucket Carriers; and I do hereby declare that the followingis a full, clear, and eXact description thereof. r

My invention has especial reference to the organization ofhoisting-bucket carriers, to provide for automatic latching andunlatching of the same at 'hoisting-stations of their tracks, and alsoto provide forautomatic catch and release of hoisted buckets withrespect to said carriers,'said invention consisting incertainpeculiarities of construction and combination'of partshereinafter particularly setA forthwith reference to the accompanyingdrawings and subsequently claimed.

" l Figure Lof the `drawings represents a ve rtical longitudinalsectionview of one of my improved hoisting-bucket carriers in con junction with its track and aportion of`a bucket; Fig. 2, a plan view ofthe carrier and track, buffer-blocks `on the track beingin horizontalsection; adFig. 3, a vertical transverse section view-indicated by lines3 3 in first figure.

Referring by letter tothe drawings, A indicates each of the rails of anoverhead track, and B a buifer-block on each rail. Arranged on thetrackare Wheels C of a carrier of ordinary construction, except as todetails hereinafter specified, said carrier having sheaves D E therewithon which to trainsuspendingand draft cables F G, pertainingto ahoisting-bucket, preferably of the'separable variety set forth in myPatent No. 667,476, of February 5, 1901.

The side plates H of the carrier are each provided with an inclinedlower recess b,and

y a curved-edge lower projecting portion c of each plate constitutes aguide leading to the recess. Spacedapart by a sleeve d on a pivot c,connecting the side plates II of the carrier, are bell-cranks I, thenormally lower arms of which"n are the heaviest and provided with stopsfgf, that'lirnit independent play of dogs J, spaced apart by a sleeve 71.on a pivot t, connecting said bell-cranks, these dogs being normallycrosswise of the aforesaid recesses in said plates. Collars d' are shownon pivot e between the bellcranks and side plates of the carrier, andcollars h are shown on pivote' bet-Ween` saidbell-cranks and the dogs inconnection therewith. The ends of curved other rod P, in connection withsaid angleplates, is arranged to oppose a curved shank L .of the'yoke L,this yoke being automatically7 lifted by movement of its shank under theopposing rod.

In practice the carrier is held at the hoisting-station of the track byengagement of latch K with rod M, and the transverse pin Q of anascending bucket is guided into recesses b of lplates H by the dependingplate projections cto pass the yielding dogs .I and eventually operateagainst the branches K' of said latch to tilt the latter free of saidrod. For the time being the dogs J prevent disengagement of thebucket-pin Q from the platerecesses of the carrier, and said carrierbeing unlatched it is free to travel with the bucket to` the dumpingstation of the track, said bucket being held in suspended connectionwith the aforesaid carrier when the dumping operation takes place,notwithstanding that there is slack of the suspending-cable inconnection with said pin. On return of the carrier and bucket to thehoisting-station of the track the latch K passes under rod M to becaught by the same, and said carrier runs back 'far enough to forceyoke-shank L under rod I, whereby the weighted end of yoke Lis lifted,and, owing to the weight of said bucket, the bellcranks I, with the dogsJ, are swung to the position shown by dotted lines in Fig. l, so thatbucket-pin Q may automatically clear the recesses b in the side plates Hof said carrier. Release of the bucket having been automaticallyeffected the carrier moves ahead a limited distance to have its latch Kcatch against the rod M, the

IOO

bell-cranks I, dogs J, and yoke L being in the meantime automaticallyrestored to normal position.

Although the branches K of latch K are herein shown between thecarrier-platcs,.it is practical and at times desirable to have themoutside of said plates.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- Y 1. A hoisting-bucket carrier having itsside plates provided with recesses arranged to be engaged by abucket-pin, bell-cranks -intermediate of the plates, dogs having limitedpivotal play on arms of the bell-cranks to be normally crosswise of the.plate-recesses, a latch in pivotal connection with the carrier havingbranches that are also crosswise of said recesses above said clogs, anda pivotal yoke with said carrier in opposition to said bell-cranks, thelatch being engagcable with a stationary catch adjacent to a stationarystriker in the path of a curved shank of the yoke.

2. A hoisting-bucket carrier having its side plates provided Withrecesses arranged to be engaged by a bucket-pin, guides to the recessesin the form of curved lower projections of the plates, bell-cranksintermediate of said plates, dogs having limited pivotal play on arms ofthe bell-cranks to be normally crosswise of the plate-recesses, a latchin pivotal connection with the carrier having branches that are alsocrosswise of the plate-recesses above said dogs, and a pivotal yoke withsaid carrier in opposition to said bell-cranks, the latch beingengageable with a stationary catch adjacent to a stationary striker inthe path of a curved shank of the tilt-yoke.

3. A hoisting-bucket-carrier track having buffer-blocks, stationary rodstransversely of the track, the carrier having its side plates providedwith recesses arranged to be engaged by a bucket-pin, bell-cranksintermediate of the plates, dogs having limited pivotal play on arms ofthe bell-cranks to be normally crosswise of the plate-recesses, a latchin pivotal connectionnwith said carrier having branches that are alsocrosswise of said recesses above said dogs, and a pivotal yoke with theaforesaid carrier in opposition to said bell-cranks, the latch beingengageable With one of Ithe aforesaid rods and the other rod arranged inthe path of a curved shank of the yoke.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Wiscousin, in thepresence of two witnesses.
